      x86/retbleed: Fix return thunk alignment · 9a48d604
      Borislav Petkov (AMD) authored
      SYM_FUNC_START_LOCAL_NOALIGN() adds an endbr leading to this layout
      (leaving only the last 2 bytes of the address):
      
        3bff <zen_untrain_ret>:
        3bff:       f3 0f 1e fa             endbr64
        3c03:       f6                      test   $0xcc,%bl
      
        3c04 <__x86_return_thunk>:
        3c04:       c3                      ret
        3c05:       cc                      int3
        3c06:       0f ae e8                lfence
      
      However, "the RET at __x86_return_thunk must be on a 64 byte boundary,
      for alignment within the BTB."
      
      Use SYM_START instead.

      Pull more btrfs fixes from David Sterba:
      
       - fix incorrect number of bitmap entries for space cache if loading is
         interrupted by some error
      
       - fix backref walking, this breaks a mode of LOGICAL_INO_V2 ioctl that
         is used in deduplication tools
      
       - zoned mode fixes:
            - properly finish zone reserved for relocation
            - correctly calculate super block zone end on ZNS
            - properly initialize new extent buffer for redirty
      
       - make mount option clear_cache work with block-group-tree, to rebuild
         free-space-tree instead of temporarily disabling it that would lead
         to a forced read-only mount
      
       - fix alignment check for offset when printing extent item

      Pull RISC-V fix from Palmer Dabbelt:
       "Just a single fix this week for a build issue. That'd usually be a
        good sign, but we've started to get some reports of boot failures on
        some hardware/bootloader configurations. Nothing concrete yet, but
        I've got a funny feeling that's where much of the bug hunting is going
        right now.
      
        Nothing's reproducing on my end, though, and this fixes some pretty
        concrete issues so I figured there's no reason to delay it:

      pipe: check for IOCB_NOWAIT alongside O_NONBLOCK · c04fe8e3
      Jens Axboe authored
      Pipe reads or writes need to enable nonblocking attempts, if either
      O_NONBLOCK is set on the file, or IOCB_NOWAIT is set in the iocb being
      passed in. The latter isn't currently true, ensure we check for both
      before waiting on data or space.
